START, OF TONAWANDA, NEW YORK, ASSIGNOR TO THECOLUMBUS- MCKINNON CHAIN CORPORATION, OF TONAWANDA, NE'W YORK, ACORPORATION OF N EW YORK MACHINE FOR STAMPING MARKS ON W'IRE OR THE LIKEApplication filed. July 5, 1929. Serial No. 376,095.

This invention relates to machines for impressing identifyingcharacterstrade-marks for exampleon rods, wire or other strands of metaland is more especially designed for 3 so marking such articles as areintended to be cut up into pieces for forming chain links.

The object of the invention is to provide improved and simplified meanswhereby the work referred to may be neatly, rapidly and i9 economicallydone.

The invention is-embodied in the example herein shown and described, thefeatures of novelty being finally claimed.

In the accompanying drawings Figure 1 is a view of themachine in sideelevation.

Fig. 2 is a top plan view partly broken out.

Fig. 3 is a side and sectional view on a larger scale of thecharacter-impressing means.

20 Fig. 4 is a top plan view of the same.

Fig. 5 is an elevation looking at the right hand end of Fig. 4.

In the views designates the frame upon which is fulcrumed at 11 a diepressing lever "having a long arm 12 and ashort arm 12. Said long arm 12is provided with a small roller 13 journaled near the end thereofactuated by a cam 14 journaled at 15 in the frame. Said cam has a highportion adapted, when 30 the cam is regularly rotated to depress theshorter arm of the lever at regular intervals.

The character-impressing means includes an anvil or stationary block 16having in its upper face a longitudinal groove for the movement of thewire, said block provided with a pin 17 for setting it inthe table ofthe frame, and a movable block 18 pivoted by the stud bearings '19 inplates 20 secured to the opposite sides of the correspondmg end of thebase block so that the upper or movable block can swing vertically onsaid bearings 19.

The upper block 18 has a longitudinal groove in its lower face to matchthe correspondinggroove of the lower block, and at its lower side theupper block also has a rect'angular recess in which is fixed themarkcontaining die block 22. The die block 22 is placed in said recessbetween two other plain filler blocks 23 and 24: also in said recess andall three are pinched tightly together by a set screw 25 in the free endof the holding block 18. By releasing the screw 25 the die block can bereplaced with a fresh one: and by suitably varying the sizes of theblocks 2?) and 2a the die or trade-marking block 22 can be differentlylocated in the recess or a larger or smaller marking block used.

Coiled springs 26, 26, having their respective ends seated in sockets inthe top and bottom blocks 16 and 18 are provided tending normally to"hold said blocks separated as shown in Fig. 3 with the marking block offthe wire or rod to be marked.

The shorter arm 12 of the die pressing lever is provided with a screw 27threaded thereonto and having a plain end to bear on top of the dieholding block 18 to depress the same to make imprint of the trade-markin the wire or rod, a piece of which is shown at 28. Said screw can beadjusted and fixed in ad usted position by a jam nut 29 to vary thedepth of the imprint to be made.

In practice mechanism operated by power can be provided to move the wirewith an intermittent movement through the grooves in the blocks 16 and18 and while the roller 13 of the longer arm 12 of the die pressin-lever is at the low part of the cam; and during the intervals of thewire feed and while the wire is at rest the marking die will bedepressed by the operating high part of the cam. I

The forms of the parts can be changed without departing from the gist ofthe invention as claimed.

lVhat I claim is:

1. Means for impressing marks on a wire or the like including a pair ofelongated blocks, one of which is stationary and provided with alongitudinal wire-guiding groove in its upper face, and theother ofwhich blocks is pivoted at one end to said stationary block to swing inrelation thereto, said pivoted block having a marking-die-receivingcavity and a groove at the pivoted end opposed to and cooperating withthe groove of the stationary block to form an entrance and guide for thewire between the pivoted ends of the blocks. a marking die carried bythe pivoted block, and means for interinittingly pressing said pivetedblock and m arking die toward the stationary block.

2. Means for impresslng marks on a Wire 01' the like including a pair ofelongated'blocks,
